摘要
Abstract
Objective:To study the effect of fluoride on the fatigue properties of Ni-Ti orthodontic wires. Method:Four different brands Ni-Ti round wires were selected for this study. For each brand, sixteen specimens were chosen that were immersed into artificial saliva and fluoride artificial saliva, respectively. After a week, the dynamic mechanics experiment was carried out until the wire was fractured. Scanning electron microscopy was used to scan the surfaces and the fracture surfaces of the Ni-Ti orthodontic wires before and after the experiment. Result:There were no statistically significant differences in fatigue property among these four Ni-Ti orthodontic wires. According to the scanning electron micrographs, spot corrosion was observed on the surfaces of Ni-Ti orthodontic wires of four brands that were immersing into both two kinds of saliva. Conclusion:The fatigue property of the Ni-Ti orthodontic wires in this study haven’t been affected by fluoride.关键词
